RNA gel blot detection of accumulation of miR172 in mature leaves of wild-type and miR172 transgenic plants. a10-2 and a16-3 were transformed with pre-MIR172a and had normal phenotype; b2-1 and b4-1 were transformed with pre-MIR172b and showed strongly altered phenotypes; b8-1 and b10-1 were also transformed with pre-MIR172b but showed moderately altered phenotypes. O/X: over-expressor.
